UD8KB100-BP

Bridge Rectifier Overview

The UD8KB100-BP is a single-phase glass passivated bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current of 8 A and a peak repetitive reverse voltage of 1000 V. The device utilizes a D3K-4 surface-mount package with solder pad termination. Electrical characteristics include a maximum forward voltage of 1.05 V at 4 A, a reverse leakage current of 100 µA at 125°C, and a non-repetitive peak surge current of 175 A. Thermal resistance from junction to case is 1.5 °C/W, supporting operation within a temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating

Bridge Rectifier Applications

• General purpose AC to DC power supply conversion
• Bridge rectifier circuits in industrial equipment
• Power adapters and chargers

Bridge Rectifier Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the BP suffix indicates RoHS compliance and halogen-free status. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Bridge Rectifier Selection Notes

Select this component for applications requiring 1000 V blocking voltage and 8 A continuous current in a compact SMD form factor. Evaluate thermal management requirements based on the specified junction-to-case resistance. Compare against alternative voltage ratings within the UD8KB series if system voltage differs.

Bridge Rectifier Part Context

This part belongs to the UD8KB series of 8 Amp bridge rectifiers covering voltage ratings from 50 V to 1000 V. The series shares identical mechanical dimensions and electrical performance profiles, differing primarily in the peak repetitive reverse voltage specification. The D3K-4 package allows for standardized footprint design across the product line.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other 8 A, 1000 V bridge rectifiers in the D3K-4 package. Verify pinout compatibility and ensure equivalent thermal and electrical ratings before substitution.
